Since the Brand Code List contains codes containing “0” while the keyboard of the device contains no “0,” I assume that the mysterious buttons labeled “1-/11” and so forth must be required to produce a “0.” More guesswork leads to the hypothesis that to enter “01” a user must press the “0/10” button three times (once for “0” and then twice to count up from “0” to “1”). This cannot be true, however, because how could one ever produce “00”? Surely some critical information has been omitted from the instructions.
